Nidoking

As long as Nidoking is in play, your attacks by Nidoran ♀, Nidorina, Nidoqueen, Nidoran ♂, and Nidorino do 10 more damage to the Defending Pokémon.

Earth Poison

If the Defending Pokémon already has any damage counters on it, the Defending Pokémon is now Poisoned.

Bound Crush

Choose 1 of your opponent's Pokémon. This attack does 60 damage to that Pokémon. (Don't apply Weakness and Resistance for Benched Pokémon.) Nidoking can't use Bound Crush during your next turn.
